The MIM/Honey

How to Mint MIM on Abracadabra, without using real collateral -

Try to add single side HONEY in the Honey/MIM pool in the Berachain BEX, then you potentially can mint MIM, see IMGs

Issues and discrepancies, might occur. From indicated RPC-failure where it doesn't create an LP and indicated failure where it does create an LP. BEX historical transactions may not update despite registering provided liquidity and value. However during the test $14 of HONEY/MIM on BEX was the equivalent of 0.008 LP < $0.01 in Abracadabra.

Meaning when it registered the LP on the Berachain BEX, less than 1 MIM was able to be minted and borrowed. Approving the token went fine.
But when attempting to go through with Mint & Borrow afterwards - Red pop-ups overriding the yellow middle-step tab, started appearing suggesting that the user rejected the transaction. It took around 20x attempts before it finally accepted the transaction attempt and allowed the yellow menu before initiating the Metamask window, and displaying the approval of 3rd party and the gas for the attempted tx thereafter to be paid after which MIM was minted..

Point being even if it indicates failure 20 times in the minting stage as of now, it can suddenly function if trying again.. #Mint #MIM #Abracadabra

BEX Swap exchange rate instability

The exchange rate of BEX Swap is unstable and has been fluctuating significantly, which is abnormal. It is recommended to follow up

Berachain is an EVM-compatible L1 blockchain built on-top of the Cosmos-SDK that supports all the same tooling, operations, and adds additional functionality built into the chain that optimizes for proof-of-“liquity” and typical abstracted use-cases (DEXs, Oracles, etc).
